JOSEPH WHITE, OF PORT HURON,` MICHIGAN.

MAGAZINE-BOILER.

SPECIFICATION' forming part of Letters PatentNo. 323,764, dated August 4, 1885.

Application filed October 22, 1884. (No model.)

To aZZ whom it may concern,.-

Beit known that I, JOSEPH WHITE, of Por Huron, in the county of St. Clair and State of Michigan, have invented new and useful Improvements in Magazine-Boilers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in the construction of boilers more especially designed for generating steam for heating purposes.

The invention consists in the peculiar construction of theparts and their operation, all as hereinafter more fully described and claimed.

i Figure l is a vertical central horizontal section through my improved boiler. Fig. 2 is a horizontal cross-section.

In the accompanying drawings, which form I a part of this specification, A represents an G is the continuation of the magazine, ex"

tending into the combustion-chamber H, and this sectlon of the magazine is made of castiron, preferably, and is secured in coincidence with the upper section, E, and to the underA side of the crown-sheet by means of bolts and lugs a in any suitable manner that will allow this section G to be removed readily shouldit be burned off and need replacing, or should it become necessary to get at the fines I, which extend horizontally from the combustionchamber through the horizontal portion J of the boiler to the jacket K. The inner cylindrical wall of the boiler A is interrupted by the flue-sheet L, which is fiat and stands vertical, as shown in Fig. 2, and is riveted to the inner shell; and this dat line-sheet enables the [lues I to be cut the saine length and more easily inserted and calked than though inserted through the circular side of the boiler.

M is a cut-o' bottom to the magazine G, and is operated by means of the -rod or lever N through the front of the boiler or through a suitable opening therein, or in the door which is designed to close the doorway O.

By means of a boiler thus constructed a supply of fuel may be regulated as easily as the supply of fuel in a magazine-stove, and the boiler will be found Very efficient, making steam for heating purposes in a sufficient quantity with a minimum of fuel; and it will be found also well adapted to burning anthracite coal.

- I amvawarc of the Patents No. 248,411 and No. 27 2,692, and make no claim to the constructions shown therein as forming part of my in'- vention.

I deem it important that the lower section, G, of the magazine project into the combustion-chamber, and that it be removably secured to the crown-sheet, for by this construction the lower section can readily be removed when the same needs to be replaced or repaired, or should it be desired vto get at the lines I.

What I claim as lny invention isl. A steamgenerator having a magazine composed of .two sections, the lower one of which extends into the vcombustionchamber and is removably secured to the crown-sheet, substantially as described, such generator being cylindrical in form and having a flat crown-sheet, in combination with the horizontal Vportion of the boiler and its iiues, substantially as specilied.

2. In a steam-generator consisting of the vertical section A, water-legs B, grate C, niagazine E G, the part `G being removably secured to thecrown-sheet F, combustion-chamber H, flue-sheet L, horizontal section J. and flues I, and the cut-off bottom M, provided with the lever N, the parts being constructed, arranged, and operating substantially as and for the purposes described.

JosEPII WHITE.
